Hello

I had a SATA drive on my linux server.
One day I woke up and all the info on the drive was gone.
It was formatted with ext3 before the data problem.

If this were Fat32, I know of a tool named Tiramisu that may have recovered it.

Are there any tools at all for linux that have the same functionality? I was very careful not to write anything on the drive afterwards, it's staying intact.

you can use all ext2 tools, like

try to copy your disk with dd, if you have bad sectors or whatever hardware problem, then

"One day, you woke up, and all the information was gone"? Surely this isn't a problem....as we all do daily backups;)

You've done the right thing by not writing any thing to this drive. Ideally, you need to work out what caused the data to vanish. I'd definitely be checking the BIOS settings are correctly.

Next try seeing if the drive exists when you boot up with either Knoppix:

www.knoppix.net

, or UBCD (if you are a windows fan:

www.ubcd4win.com

If it does, then ideally you need to make an image of the drive to an external Hard drive, or additional backup drive, or network drive that you have access to.

If not, then you may need to check that the BIOS configurationand any other hardware connections to the drive are correct. If that doesn't work, then you may need another working system in order to ensure that you have a greater array of software diagnostics, and use some of the recovery tools already mentioned.
